Just got a new monitor, an ASUS ProArt PA32QCV. First time I've had a high density display for my Windows desktop. It's nice!
(Eloi friends, you are welcome to mock me on this one: it took Windows forever to catch up on Retina and it's still behind.)

Hawking-Page transition in anti-de Sitter massive gravity with non-compact spatial boundary
In gauge/gravity duality, the Hawking Page (HP) process plays the important role of representing a confined/deconfined phase transition. For spaces that are asymptotically anti-de Sitter (AdS) with planar spatial boundary there is no HP transition, unless some infrared energy scale is introduced. Massive gravity theories have been applied in the context of holography in order to represent systems with momentum dissipation. In this work we study the HP transition for massive gravity in an asympt…

Functional Donoho-Elad-Gribonval-Nielsen-Fuchs Sparsity Theorem
Celebrated breakthrough sparsity theorem obtained independently by Donoho and Elad \textit{[Proc. Natl. Acad. Sci. USA, 2003]} and Gribonval and Nielsen \textit{[IEEE Trans. Inform. Theory, 2003]} and Fuchs \textit{[IEEE Trans. Inform. Theory, 2004]} says that unique sparse solution to NP-Hard $\ell_0$-minimization problem can be obtained using unique solution to P-Type $\ell_1$-minimization problem. In this paper, we extend their result to abstract Banach spaces using 1-approximate Schauder fr…

Bilevel optimization for learning hyperparameters: Application to solving PDEs and inverse problems with Gaussian processes
Methods for solving scientific computing and inference problems, such as kernel- and neural network-based approaches for partial differential equations (PDEs), inverse problems, and supervised learning tasks, depend crucially on the choice of hyperparameters. Specifically, the efficacy of such methods, and in particular their accuracy, stability, and generalization properties, strongly depends on the choice of hyperparameters. While bilevel optimization offers a principled framework for hyperpa…

Asteroseismic investigation of HD 140283: The Methuselah star
HD 140283 is a well-studied metal-poor subgiant and a Gaia benchmark star, often used for testing stellar models due to its proximity, brightness, and low metallicity ([Fe/H] = -2.3 dex). Here we present the first asteroseismic analysis of HD 140283, providing improved constraints on its fundamental properties. The star was observed by TESS in 20-second cadence during Sector 51. We extracted a custom light curve and performed a frequency analysis, revealing a rich spectrum of solar-like osc…

Mit einem persönlichen Kalender will Steam Nutzer über bevorstehende Veröffentlichungen informieren. Die Spiele wählt Valve dabei nach Spielerprofil aus.

Wikipedia informs me Jabberwocky was originally a parody of Anglo-Saxon Poetry and þis form is delightful.
Twas bryllyg, and þe slythy toves
Did gyre and gymble in þe wabe:
All mimsy were þe borogoves;
And þe mome raths outgrabe.

Once again impressed by WiThings. Just bought a new Body Comp scale and it's a lovely new product experience. Their software quality is excellent. Just a great experience.
(And a big raspberry to InBody: did not like their comparable product.)

Just set up Plexamp and am really impressed. Basically gives me a Spotify-like experience with my own personal music collection. Loving the "play music of this genre" and "this mood" features. It's a nice complete product, a pleasant addition to Plex.
